Where does that notion come from? It's within the Jurisdiction of the government of the United States, that makes it within the jurisdiction of the federal and state courts, if they are functioning, which they clearly are. Doesn't mean this judges decision is right. In fact, now that I think about it, the Fifth Circuit may not be functioning, unless it's set up in Houston, because it's normal location is New Orleans, which is less than a mile (in the drier direction) from the Superdome. Otherwise a federal district judge in Texas does not have jurisdiction in Louisiana.
I forgot to include a "/sarc" tag on my post. There has been so much posted about so-called "martial law" and so many conflicting news reports about the actual "legal" status under which "the Authorities" are operating that the concept of "rule of law" is pretty much a joke.
If anyone has noticed, "the Authorities", at all levels, have managed to sufficiently obfuscate, diffuse and disguise any semblance of a clear chain of command and responsibility. The has the tremendous benefit of allowing them maxiumum power and freedom of action with minimal, almost non-existant accountability.
The hypocrisy of demanding the "Constitutional right" to show the bodies of the dead, while simultaneously refusing to stand up for the Constitutional rights of the living who survived speaks for itself.
If surviving. law-abiding property owners can be summarily denied their Constitutional right to defend their lives and property because of "the Emergency", then the media can certainly be denied access to broadcast the pictures of the dead to satisfy the ghoulish lusts of a decadent populace.
You can't have it both ways, at least not morally, logically or lawfully.
